On PowerTak with Lorraine Jacque-White the topic of discussion was the devastating act of an Former Navy Reservist who killed at least 12 people on Monday in Washington D.C in a mass shooting at a secure military facility. This led the authorities to lock down part of the nation’s capital — even after the gunman was killed. The federal authorities said they believed the shooting was the act of a lone gunman, identified as Aaron Alexis, 34, who was working for a military subcontractor.

Police officers who swarmed the military facility exchanged fire with Mr. Alexis, 34, a former naval reservist in Fort Worth. Police officers shot Mr. Alexis to death, law enforcement officials said, but not before a dozen people were killed and several others, including a city police officer, were wounded and taken to local hospitals.

“He was shooting down from above the people,” one law enforcement official said. “That is where he does most of his damage.”

Three weapons were found on Mr. Alexis: an AR-15 assault rifle, a shotgun and a semiautomatic pistol, It was unclear whether he had brought all the guns with him, or if he had taken one or more of them from his victims. Officials said they were still searching for a motive as they asked the public for help by posting pictures of Mr. Alexis on the F.B.I. Web site. The agency is treating the shooting as a criminal investigation, not one related to terrorism.

Our PowerTalk audience was very shock to find out that Alexis was an African American male some even felt some form of sympathy for him.
